Elder Scrolls IV: Oblivion is a first-person perspective fantasy computer role-playing game set in a vast 3D world with an open-ended storyline that allows the player the freedom to pursue the main quest, side quests, or simply explore the world. The game is set in a different geographic location from the previous in the series (Elder Scrolls III: Morrowind) and in general the architecture and wildlife is more medieval and real-world. The fantasy game art is vastly improved, however, and at the time of its release wowed the world with its realism and attention to physics in its interactivity.

Hentai Mania 1: Princess of the Sorrow is an Elder Scrolls IV: Oblivion mod that replaces the adversaries in various non-essential forts and ruins in with sexy, dangerous, babes in outfits completely different from what is normally available in Oblivion.

The Armor of Vacant is worn by the "Servants of Void", who have a short and somewhat squat looking "super-deformed" look. If they are slain, however, their body shape reverts to regular proportions. This does not affect the player if they wear this armour.
